IMPROVEMENT IN DITCHING AND TILE-LAVING MACHINES.

Specification forming part of Letters Patent No. 156,451, dated November3, 1874; application tiled September 1, 1874.

`of Ohio, have invented certain new and useful Improvements in Ditchingand Tile-Laying Machines 5 and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification. l

The nature of my invention consists in the construction and arrangementof a machine for digging ditches and laying tiles, as will behereinafter more fully set forth.

In order to enable others skilled in the art to whichmy inventionappertains to make and use the same, I will now proceed `to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view, and Fig. 2 `a side elevation, of my machine.

A represents the plow-beam, provided at its front end with any ordinaryclevis, B, to which the team is to be hitched. On the beam A are securedtwo parallel cross-beams, C C, the ends of which are connected by bars cc, secured thereto by clips b b. D represents the plow, which is made inthe shape shown, being flat on its under side, and the upper sideinclined upward from the point backward for a suitable distance, andfrom such point the upper surface runs parallel with the lower, as shownin Fig. 2. The upper surface of the plow D increases in width from thepoint to where the inclination ceases, in such a de gree that thehorizontal part of the plow shall be double, or more than double, thewidth of the point of the plow. From near the point of the plow inclinedcutters E E extend to the bars a, to which they are fastened by clips d.G is a rear colter, attached to the plow, and passing up through thebeam A. This colter has a series of notches, in its rear edge, and isheld by a latch, f, pivotedV on the plowbeam, and entering either ofsaid notches, to

n hold the plow at any desired distance from the beam. In rear of thecolter G is the tiletube H, secured to the plow D, and held to the rearend of the beam A by two metal bars, h, attached vto said beam, andpassing, one on each side of the tube. A plate or bar, e, is passed overthe ends of the rods h, and screws c' placed on the ends thereof,whereby the tube is held firmly, and can easily be adjusted up and down,as desired. Along the rear side of the tube H are inserted guides fm,which arc to be changed according to the size of tile to be laid.Through the fro'nt end of the beam A passes a vertical revolving colter,I, provided at its upper end with a lever or handle, J, for turning thecolter, and hence the plow, around. curves.

The inclined side colters E E cut the sides of the ditch the same width,and the plow raises the earth to a certain height, when the centercolter G cuts the thus raised earth in the center. The tube H thenpresses the earth toward both sides, and at the same time the tiles arefed downthrough the tube H, and as the plow passes on the earth fallsdown back of said tube, covering the tile.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is- Y 1. The combination of theditching-plow D and tile-tube H with adjustable guides m., to receivethe tile vertically, and the center colter G, all as and for the purposeset forth. I

2. The combination of the frame A C c,

plow D, tile-tube H, center colter G, side colters E E, and adjustablecolter I, all constructed substantially as and for the purposes hereinset forth. v

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
